SIGNAL.

Specification of Letters Patent.

Patented July 20, 1909.

To all whom it may concern:

Be it known that we, JAMES M. KENNEDY and IRVIN W. GLEAsoN, citizens of the United States, residing at Lewisburg and Gleasonton, counties of Union and Clinton, respectively, and State of Pennsylvania,have invented a certain new and useful Improvement in Signals, of which the following is a specification.

Our invention relates to a new and useful improvement in signals, and especially to that class of signals which are used in notifying the engineer of a train thatthe train pre ceding him is blocked, or that some accident has occurred, which requires him to bring his train to a stop.

Another object of our invention is to provide a device of this character which will notify the engineer by means of the air whistle should there be a storm which would hide the signals or the flagman.

With these ends inview, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, we will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which Figure 1 is a view half in elevation and half in section of our improved signal. Fig. 2, a longitudinal sectional view thereof. Fig. 3, a side elevation of the detachable contact member, and Fig. 4, a sectional view at the line a:m of Fig. 3.

In carrying out our invention as here embodied, A represents a casing journaled on the shaft B, and fastened thereon by the nut C threaded on the end of the shaft B. This casing is provided at the bottom thereof with a lug D adapted to come in contact with a suitable contact member to be hereinafter described.

Secured to the inside of the casing A is a toothed segment E, the teeth of which are adapted to engage with the teeth of the pinion F, said pinion being secured to the shaft G of the valve H, having the opening I formed therein. The valve H is placed in the pipe J leadin from the compressed air or steam tank to t e whistle.

K represents a second casing having the brackets L formed therewith so that it may be fastened to any desirable part of the engine, and the flange of this casing is adapted to fit within the flange of the casing A, a portion of the flange of the casing K being cut away as indicated by M, so as to allow the free movement of the casing A, which is provided with a lug N near its upper end. The casing K is provided with a lug O, to which is fastened the flat spring P, the free ends of said spring resting against the lug N formed with the casing A, so that when the casing A has been drawn to one side through the extension D coming in contact with a suitable contact member it will be brought back to its original position as soon as it disengages from said contact member.

Q denotes a detachable. contact member composed of the base It, having one end turned up to form the finger S, which is adapted to fit over the bottom flange of the rail, and the other end is turned up at right angles to form the arm T, and this arm is again bent at right angles to form the extension U, which runs parallel with the base E. This base is provided with a slot Vthrough which asses the bolt W, which also passes through the sliding member Y, said sliding member having a finger Z formed therewith similar to the finger S formed with the base, so that it will fit upon the opposite side of the bottom flange of the rails. Secured to the sliding member Y is a cam Y, against which rests the cam wrench Y The belt V also passes through the cam and the cam wrench and the nut Y is then threaded thereon which holds the arts together.

In ractice w en it is desired to stop a train y notifying the engineer the contact member Q is placed on the track, the fingers S and Z fitting upon the bottom flanges of the rail, and when the right adjustment has been acquired by the sliding member Y, the cam wrench Y is turned, which tightens the arts andholds the contact member securely to the track. When the train reaches the point at which the contact member is placed, the lug D will come in contact with the extension U swinging it to one side, which will do likewise with the toothed segment E, thus revolving the pinion F, which will turn the valve H until the opening I therein is in a vertical position, which will allow the air or steam to pass through the ipe J from the supply tank to the whistle, b owing the same, thus notifying the engineer that he must stop his train.

Of course we do not wish to be limited to the eXactdetails here-shown as thesemay-be varied within certain limits without departing from the spirit of our invention.

Having thus fully described our invention, what We claim as new and useful, is

1. In combination with a pipe leading. from a supply tank to a whistle, of a valve, a shaft formed with said valve, a pinion secured to said shaft, a casing having a lug formedwith thelower-portionthereof and a lugformedwitlr theinner surface of the upper portion thereof, a toothed segment secured to said casing, the teeth of which are adapted to: engage with the teeth of the-pinion, and-meansfor tu rningsaidicasing so that the valve will be turned, substantially as shown and. described.

2. In combination with a shaft, a casing having-an inner lug and an-outcr lugform'ed therewith journalecl on said shaft, a toothedsegrment secured to the'inner' surface of said casing; a valve journaled in a pipe=leading from a su ply tank to: a whistle, a shaftformed wit said valve,"a pinion secured-to said'shaft, the teeth of which-engage with the teeth of the toothed segment, a second casing having a portion of the flange thereof cut away provided with external brackets' and aninternal lug, "and a flat spring secured to said lug, the free end of which rests against the internal lug=formed with the first named casing.

3. In combination with a shaft, acasinghavingan inner lug and an outer lug formed therewith j'ournaled on-said shaft, a toothed segment secured to the "-innersurface of said casing, a valve journaled in'a' pipe leading 7 from a su ply tank to a'whistle, a shaft formed with said valve, a pinion secured tosaid shaft, the teeth of which engage with the teeth of the toothed segment, 'a-second-oasing having a portion of the flange thereof cut away provided with external brackets and an internal lug, a flat spring secured to said lug,

the free end of whichrests against the interfrom a supply tank to a whistle, a shaft formed with said valve, a inion secured to said shaft the teeth of whic engagewith the teeth of the toothedsegment, a second casing having a portion of the flange thereof cut away provided with external brackets and lug, the free-end of which rests against the internal lug formed with the first named casing, a detachable contact member with which the lugformed on the lower portion of theflrstnamed casing is adapted to come in contact, said contact member being formed to'produ'cea base-havinga slot formed there an internal lug, a flat spring secured to said in, one end of saidbase beingbent-to' form. a

finger,-'the opposite end being bent-at right angles to form an arm, this arm being bent. at right angles to form an extensioma sliding member provided with a finger and a earn, a

canrwrench adapted'to rest against the cam,

a bolt passingthrough a slot in thebase, the

I sliding member, cam and cam wrench and a nut threaded onsaid boltfor holding the parts together, asshownand described.

In testimony whereof, we have hereuntoaffixed our signatures in the presence of two subscribing witnesses.
